Configuration: Disk Groups and Virtual Disks

You can change the RAID controller module ownership of a virtual disk or a 

disk group.
You can change the RAID controller module ownership of a standard virtual 

disk or a snapshot repository virtual disk. You cannot directly change the 

RAID controller module ownership of a snapshot virtual disk because the 

snapshot virtual disk inherits the RAID controller module owner of its 

associated source virtual disk. Changing the RAID controller module 

ownership of a virtual disk changes the preferred RAID controller module 

ownership of the virtual disk.
During a virtual disk copy, the same RAID controller module must own both 

the source virtual disk and the target virtual disk. Sometimes both virtual 

disks do not have the same preferred RAID controller module when the 

virtual disk copy starts. Therefore, the ownership of the target virtual disk is 

automatically transferred to the preferred RAID controller module of the 

source virtual disk. When the virtual disk copy is completed or is stopped, 

ownership of the target virtual disk is restored to its preferred RAID controller 

module. If ownership of the source virtual disk is changed during the virtual 

disk copy, ownership of the target virtual disk is also changed. Under certain 

operating system environments, it might be necessary to reconfigure the 

multi-path driver before an I/O path can be used.

1 Do you want to change the RAID controller module ownership of a virtual 

disk or a disk group?
• Change the RAID controller module ownership of a virtual disk – Go 

• Change the RAID controller module ownership of a disk group – Go 

2 To change the RAID controller module ownership of a virtual disk, 

perform these steps:

Select the Logical tab.

Select the virtual disk.

Select Virtual Disk Change Ownership/Preferred Path. 

Alternatively, you can right-click the virtual disk and select 

Change 

Ownership/Preferred Path from the pop-up menu.
